FlameThrower Stackburger

What is it?

Two seasoned beef patties sit under jalapeño bacon, pepper jack cheese, and FlameThrower sauce in Dairy Queen’s Signature Stackburger lineup. The heat comes in layers, from the bacon itself, the cheese, and a tangy sauce that spreads the spice around instead of keeping it in one spot. It’s built like a standard double cheeseburger, but with a sharper, more peppery profile than the milder Stackburgers around it. Bacon adds smoky salt, while the pepper jack melts into the patties and the sauce brings a vinegary kick. Compared with the rest of the DQ burger lineup, this one leans hardest into heat without changing the basic fast-food burger format.
